چکیده

In the past few years, there has been much interest at JPL in the investigation and development of efficient signal arraying techniques. As JPL missions begin to adopt Ka-band (32-GHz) for downlink communications, and the mechanical control and structural integrity of large antennas approach their limits, using advanced signal processing to array smaller antennas becomes a cost effective and flexible option for the Deep Space Network (DSN) to meet its current and future needs. Arraying can be applied to the feed horn at the front end of the antenna to increase the efficiency of the front end, to perform atmospheric noise cancellation, and to assist antenna pointing [1–4]. It can also be applied to intraand inter-complex antenna arraying to increase the effective aperture, for example, in full spectrum combining, complex symbol combining, and symbol combining [5,6]. The effects of colored noise on full spectrum combining and complex symbol combining have also been analyzed [7].

Optimal Locating and Sizing of Unified Power Quality Conditioner- phase Angle Control for Reactive Power Compensation in Radial Distribution Network with Wind Generation

In this article, a multi-objective planning is demonstrated for reactive power compensation in radial distribution networks with wind generation via unified power quality conditioner (UPQC). UPQC model, based on phase angle control (PAC), is used. In presented method, optimal locating of UPQC-PAC is done by simultaneous minimizing of objective functions such as: grid power loss, percentage of n...

A Unique Approach of Noise Elimination from Electroencephalography Signals between Normal and Meditation State

In this paper, unique approach is presented for the electroencephalography (EEG) signals analysis. This is based on Eigen values distribution of a matrix which is called as scaled Hankel matrix. This gives us a way to find out the number of Eigen values essential for noise reduction and extraction of signal in singular spectrum analysis. This paper gives us an approach to classify the EEG signa...

Suppression of Chaotic Behavior in Duffing-holmes System using Backstepping Controller Optimized by Unified Particle Swarm Optimization Algorithm

The nonlinear behavior analysis and chaos control for Duffing-Holmes chaotic system is discussed in the paper. In order to suppress the irregular chaotic motion, an optimal backstepping controller is designed. The backstepping method consists of parameters with positive values. The improper selection of the parameters leads to inappropriate responses or even may lead to instability of the syste...

Optimizing image steganography by combining the GA and ICA

In this study, a novel approach which uses combination of steganography and cryptography for hiding information into digital images as host media is proposed. In the process, secret data is first encrypted using the mono-alphabetic substitution cipher method and then the encrypted secret data is embedded inside an image using an algorithm which combines the random patterns based on Space Fillin...
